2.2 Power Supply

The power supply for the blu2i Module has to be a single voltage source of Vcc= 3.6V to 6V. It must be able to provide sufficient current in a transmit burst which can rise to 65mA.

The module includes regulators to provide local 3.3V and 1.8V. These rails are accessible on connector J2 for monitoring.

Power (Vcc) should be provided via the board-to-board connector Pin 29 on J2.

Section 5.3 details the power consumption in different modes.

2.3Power-On-Reset (Power Cycling and Brown Out considerations)

The Module is provided with an active high reset pin (Hirose 40 way DF12C connector pin 13). This pin whose electrical specification may be found in section 3.3 is internally pulled to ground through a 10KΩ resistor. Upon the application of power, the Power On Reset circuit built into the module will ensure that the unit starts correctly.

However the module utilises a split rail design with some components working at 3V3 and some at 1V8. Under certain extreme conditions, for
